Best Outdoor Heater for Restaurants Buying Guide

Heater Type: Propane vs. Electric

The first decision is power source. Propane models (like many used in grills and smokers) offer high heat output, often 40,000, 50,000 BTU, and are ideal for large, open patios. They run on refillable tanks, so you need storage and ventilation.

Electric infrared heaters are quieter, odorless, and easier to install, especially for covered or semi-enclosed spaces. They typically output 1,500W (about 5,100 BTU) and are best for smaller areas or as supplemental heat. Consider your patio’s size and enclosure when choosing.

For restaurant patios, propane units are common because they produce powerful, radiant heat that works well in windy conditions. Electric models, especially wall-mounted or standing infrared, are gaining popularity for their zero emissions and lower maintenance.

Always check local fire codes and ventilation requirements before installing any heater in a commercial setting.

Heat Output and Coverage Area

Heat output is measured in BTU for propane heaters and watts for electric ones.

A general rule: a 46,000 BTU propane heater can warm an area of about 100, 150 square feet under a covered patio, while a 1,500W electric heater covers roughly 50, 80 square feet.

For open or windy spaces, you may need multiple units or higher BTU. Look for models with adjustable heat settings so you can tailor warmth to different zones.

Many top-rated picks in our list offer coverage suitable for restaurant terraces and sidewalk cafes.

Safety Features and Durability

Safety is paramount in a commercial environment. Essential features include tip-over shutoff (for portable units), overheat protection, and IP rating for water resistance. For outdoor use, look for at least IP44 (splash-proof) or IP65 (water-jet resistant).

Many of our recommended heaters, including those from fire pits and patio heaters, meet these standards. Also consider materials, stainless steel or rust-resistant finishes ensure longevity against rain and humidity.

For propane models, CSA or ETL certification indicates compliance with safety standards.

In restaurants, heaters are often left unattended for hours. Reliable automatic shutoff in case of tip-over or overheating is non-negotiable. Electric heaters with a grounded plug and sealed elements offer extra peace of mind. Always secure heaters to prevent accidents, especially in high-traffic areas.

Portability and Installation

Consider how you’ll set up the heater. Freestanding propane heaters with wheels, like the popular 46,000 BTU models, are easy to move around. Wall-mounted electric units save floor space and are ideal for permanent setups under awnings or pergolas.

Tabletop heaters are great for small tables or bars. If you need flexibility, choose a portable model with a stable base. Many of our picks pair well with existing patio furniture layouts.

For wall-mounted heaters, ensure the mounting surface can support the weight and that electrical outlets are nearby.

Noise and Aesthetics

In a restaurant setting, noise can affect the dining experience. Propane heaters sometimes produce a low hum from the fan or regulator, but many modern units are nearly silent.

Electric infrared heaters operate without any fan noise, making them ideal for intimate settings. Aesthetics matter too, choose a heater that complements your décor, from sleek bronze towers to minimalist wall panels.

Our selection includes options in various finishes to blend with your restaurant’s vibe.

Frequently Asked Questions

How many BTUs do I need for a restaurant patio?

For a covered patio of about 100, 150 square feet, a 40,000, 50,000 BTU propane heater is typically sufficient. For smaller spaces or electric models, 1,500W (≈5,100 BTU) covers around 50, 80 square feet. Wind, ceiling height, and insulation also affect coverage.

It’s often better to have multiple smaller heaters than one oversized unit to avoid hot spots.

Can I use an electric outdoor heater in rain?

Yes, if it has a suitable IP rating. Look for IP44 or higher for splashes; IP65 is fully water-jet resistant. Electric heaters with sealed heating elements and a grounded plug are safe for covered patios, but avoid direct downpour.

Always follow manufacturer instructions and local regulations.

Are propane heaters safe for commercial use?

Yes, when properly installed and ventilated. Choose models with tip-over shutoff and CSA/ETL certification. Keep them away from flammable materials and ensure propane tanks are secured. Many restaurants use them successfully, but check your local fire codes.

For more on propane appliances, see our propane barbecue grill guide for insights on safe usage.

What is the best way to mount a wall heater?

Wall-mounted heaters should be installed on a solid wall (concrete or brick) away from direct water spray. Use the included brackets and ensure the unit is level. For electric models, hardwiring or plugging into a GFCI outlet is recommended.

If precise heat control matters, consider models with thermostats similar to those found in smokers with temperature control for even heat distribution.

How much does it cost to run a patio heater?

Electric heaters cost roughly $0.15, $0.30 per hour at average electricity rates. Propane heaters consume about $1, $2 per hour depending on tank size and local propane prices.

For a restaurant using heaters for several hours daily, electric models offer lower operational costs but require sufficient electrical capacity. Our picks range from budget-friendly to premium, helping you balance upfront and running costs.
